Which choice correctly identifies a key characteristic of occupational injuries?

A key characteristic of occupational injuries is that they are often the result of repeated strain or stress stemming from specific work conditions. This aspect highlights that these injuries can accumulate over time due to the nature of the work environment or the demands placed on workers.

For instance, individuals performing repetitive tasks or those exposed to hazardous conditions can develop chronic issues such as musculoskeletal disorders. This understanding is crucial in occupational health as it emphasizes the need for employers to recognize and address potential hazards within the workplace that could lead to such injuries.

In contrast, injuries from accidents are generally more acute and can fall under broader categories not limited to occupational settings, while incidents outside of work or from sports activities do not pertain to occupational injuries at all. Hence, recognizing repeated strain or stress as a defining characteristic allows for a better focus on prevention and safety measures in work environments.
